I installed the JPackage java-1.4.2-sun-1.4.2.06 RPM, and now many of the Java sites that I visit crash Firefox. I am using firefox-1.0-2.fc3. Running from the command line shows the following. [mjs@vincent52 ~]$ firefox *** glibc detected *** double free or corruption (fasttop): 0x081d3ff0 *** An example site that illustrates the failure: http://www.princeton.edu/~rvdb/JAVA/pivot/simple.html Not every applet causes the failure. For example, a non-interactive applet at http://www.princeton.edu/~rvdb/ loads and runs with no problem. Anyone else experiencing this? How can I get more information to isolate whether this is a Firefox or Java issue? -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu http://www.math.clemson.edu/~mjs
